I was lurking on the HSN board for info about a possible Lancome TS. Came across an interesting thread on WEN - poster was wondering if HSN would ever sell WEN, poster thought because she was seeing Wen offered in other places that the contract with QVC might be up. Ok, so with most products on QVC, you can buy them other places so I doubt there is any contract issues (also doubt that Wen would ever go to HSN). There were some negative posts about Wen, or course right? I am an avid 613 user myself. Love it. Just gave my choco lab a bath in it this morning 
Anyway - one of the replies over there stated that the Wen sold on the guthy renker infomercial is a "different forumula" than what is sold on QVC. I know that infomercial sells the sweet almond mint forumula, but I kinda doubt that the formulation itself is any different. Anyone know anything more about this?
